To provide an Internet-based service that enables particular information receivers published on a website to selectively receive specialized information transmitted to them by particular information transmitters published on the website.

A website is set up on the Internet. Groups of schools registered in a server are published on the website and disclosed as information transmitters for information receivers, and the groups of schools and cram schools registered in the server are published on the website and disclosed as information receivers. With an information transmission and selective reception apparatus, when information arises, the information transmitters can transmit the information quickly by sending the information to the server via a mail function, and the information receivers can acquire information selectively by setting in advance in the server one or more required types from elementary schools, junior high schools, senior high schools, colleges and universities, and regions.
